Modification of vermiculite by polymerization and carbonization of glycerol to produce highly efficient materials for oil removal

Impregnation and reaction of glycerol (Gly) on the surface of expanded vermiculite (EV) was used to produce a highly efficient absorbent to remove water spilled oils. The vermiculite was impregnated by glycerol containing 1, 2 and 4 mol% of H 2SO 4 at EV/Gly ratios, i.e. 1/1, 1/2 and 1/3, and heated...
